1. Dmp53, basket and drICE gene knockdown and polyphenol gallic acid increase life span and locomotor activity in a Drosophila Parkinson's disease model
Understanding the mechanism(s) by which dopaminergic (DAergic) neurons are eroded in Parkinson's disease (PD) is critical for effective therapeutic strategies. By using the binary tyrosine hydroxylase (TH)-Gal4/UAS-X RNAi Drosophila melanogaster system, we report that Dmp53, basket and drICE gene knockdown in dopaminergic neurons prolong life span (p < 0.05;

2. Proposta e avaliação de um modelo computacional de gerador central de padrões / Proposal and evaluation of a computational model of Central Pattern Generator
The concept of Central Pattern Generator-CPG can be described as neural network capable of producing coordinated rhythmic locomotor activity apart from any external rhythm or sensorial stimuli. As this group of neurons are autonomic and are located in the spinal medulla, is experimentally observed that brainless animal‟s exhibit robotized locomotor act

4. Gerador de estímulos visuais naturalísticos para pesquisar o sistema visual de moscas / Naturalistic visual stimuli generator for research in the blowflys optical system
Este trabalho descreve o desenvolvimento e a validação de um gerador de estímulos visuais naturalísticos, GEN, utilizado em experimentos com o sistema visual de moscas. Tal gerador projeta a imagem em um anteparo que abrange todo o campo visual da mosca. Um espelho acoplado a um motor linear movimenta a imagem horizontalmente de acordo com velocidades pr

5. Mechanism for food avoidance learning in the central pattern generator of feeding behavior of Pleurobranchae californica
Food-avoidance conditioning in the mollusk Pleurobranchaea results in suppression of the feeding response to food stimuli. In conditioned animals, identified interneurons of the central pattern generator (CPG) for feeding behavior, the Int-2s, respond to a food stimulus with greater and more long-lasting excitation than controls. Enhanced Int-2 responsivenes

6. Comparison of directional selectivity in identified spiking and nonspiking mechanosensory neurons in the crayfish Orconectes limosus.
We have recorded electrical activity from two identified synaptically coupled mechanosensory interneurons in the abdominal nervous system of the crayfish Orconectes limosus and have studied their responses to constant-velocity water-jet stimuli presented from different directions. The two neurons, the ascending caudal photoreceptor (CPR) and the local direct

7. Pain-related somatosensory evoked potentials in cortical reflex myoclonus.
To elucidate the sensitivity to pain stimuli in patients with cortical reflex myoclonus, pain-related somatosensory evoked potentials (pain SEPs) following CO2 laser stimulation and conventional electrically-stimulated SEPs (electric SEPs) were compared in four patients with cortical reflex myoclonus. The P25 peak of electric SEPs was considerably enhanced b

8. Molecular and functional remodeling of electrogenic membrane of hypothalamic neurons in response to changes in their input
Neurons respond to stimuli by integrating generator and synaptic potentials and generating action potentials. However, whether the underlying electrogenic machinery within neurons itself changes, in response to alterations in input, is not known. To determine whether there are changes in Na+ channel expression and function within neurons in response to alter

9. Effect of synchronous activation of medullary inspiratory bulbo-spinal neurones on phrenic nerve discharge in cat.
The effects on phrenic nerve discharge elicited by intraspinal stimulation which produced synchronous activation of bulbo-spinal inspiratory neurones were investigated in chloralose-urethane anaesthetized, paralysed, vagotomized and artificially ventilated cats. Descending respiratory axons were activated in the ventrolateral spinal cord at the second cervic
